Therapeutic effects of bryostatins, bryologs, and other related substances on head trauma-induced memory impairment and brain injury
The invention provides for the use of protein kinase activators or boosters of nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF) or other neurotrophic factors to treat head trauma. Specifically, the present invention provides methods of treating head trauma comprising the steps of identifying a subject having suffered a head trauma and administering to said subject an amount of a pharmaceutical composition comprising a protein kinase C (PKC) activator or 4-methylcatechol acetic acid (MCBA) and a pharmaceutically acceptable carrier effective to treat at least one symptom of head trauma.
1. A method of treating post-head trauma memory deficits resulting from brain injury comprising the steps of identifying a human subject having suffered a brain injury resulting from head trauma and administering to said subject an amount of a pharmaceutical composition comprising a protein kinase C (PKC) activator, and a pharmaceutically acceptable carrier effective to treat at least one symptom of head trauma, wherein the PKC activator is chosen from
wherein R is t-Bu, Ph, or (CH 2 ) 3 p-Br-Ph, and
wherein the administration is initiated within 3 days of the head trauma and is continued for a duration in a range from about 1 week to about 12 weeks.
2. The method of claim 1 , wherein the PKC activator has a molecular weight from about 600 to 755 and an affinity for PKC from about 0.25 nM to 10 μM.
3. The method of claim 1 , wherein said administration is initiated within 1 day of said head trauma.
4. The method of claim 1 , wherein said administration is initiated within 2 days of said head trauma.
5. The method of claim 1 , wherein said administration is initiated within 3 days of said head trauma.
6. The method of claim 1 , wherein said administration is initiated between 1 and 2 days of said head trauma.
7. The method of claim 1 , wherein said administration is initiated between 1 and 3 days of said head trauma.
8. The method of claim 1 , wherein the treatment is continued for a duration of 1 week.
9. The method of claim 1 , wherein the treatment is continued for a duration of 2 weeks.
10. The method of claim 1 , wherein the treatment is continued for a duration of 3 weeks.
11. The method of claim 1 , wherein the treatment is continued for a duration of 4 weeks.
12. The method of claim 1 , wherein the treatment is continued for a duration of 6 weeks.
